2.0 SAFETY
DANGER
An inadequate supply of nozzle pressure and/or fl ow will cause an ineff ective stream and can
result in injury, death, or loss of property. See fl ow graphs or call 800-348-2686 for assistance.
WARNING
This equipment is intended for use by trained personnel for fi refi ghting. Their use for other
purposes may involve hazards not addressed by this manual. Seek appropriate guidance and
training to reduce risk of injury.
WARNING
WARNING Injury can result from an inadequately supported monitor. The monitor mount must
be capable of supporting 661 lbs (301 kg)
of nozzle reaction force.

WARNING
Some volatile liquids can be ignited by static discharge.
Static build-up can occur from:
• Electrochemical separation of charge as water drains through low conductivity, refi ned
products
• Applying foam over a low conductivity liquid of suffi
cient depth to retain the charge created as
the foam blanket drains
• Streaming currents as water or foam is introduced into the storage tank
1
WARNING
Water is a conductor of electricity. Application of water solutions on high voltage equipment can
cause injury or death by electrocution. The amount of current that may be carried back to the
nozzle will depend on the following factors:
• Voltage of the line or equipment
• Distance from the nozzle to the line or equipment
• Size of the stream
• Whether the stream is solid or broken
• Purity of the water
2
WARNING
The stream exiting a nozzle is very powerful and capable of causing injury and property damage.
Make sure the nozzle is securely attached and pointing in a safe direction before water is turned
on. Use care in directing the stream.
WARNING
The nozzle may be damaged if frozen while containing signifi cant amounts of water. Such damage
may be diffi
cult to detect visually and can lead to possible injury or death. Any time the nozzle is
subject to possible damage due to freezing, it must be tested by qualifi ed personnel before being
considered safe for use.
CAUTION
Nozzle must be mated to a hose with matched threads. Mismatched or damaged threads may
cause nozzle to leak or uncouple under pressure and could cause injury.
CAUTION
Do not connect aluminum to brass or brass to aluminum. Dissimilar metals coupled together
can cause galvanic corrosion that will freeze the threaded joint or cause complete loss of thread
engagement. If dissimilar metals must be coupled together, the eff ects of corrosion can be greatly
delayed by various coatings on the metal such as powder paint, hard anodizing, or silicone grease.
NOTICE
To prevent mechanical damage, do not drop or throw equipment.
